My understanding is that there are only around 5 threads for the plug to attach to already. Could I have really have pushed it that far down?
I used the insert with 5 normal threads and two perforated threads. I'm almost certain I was all the way down when tapping the hole. The tap is a two stage tap (my description)with the actual tap threads starting at around an inch. The inch in front of the tap threads have threads that the helicoil screws to and then the whole unit is placed in the hole to be screwed in, after applying thermal compound.
So I know I tapped as far as it would go because it stopped. However after screwing in the helicoil and suspecting I had gone maybe 1 thread too deep, I backed it out and had less than 1 threads worth of shavings in the stuck to the grease. And I just tried to budge the insert down as a test and could feel more tapping, and I pulled up just a very few small shavings again.
I know I prob need a horoscope to confirm exactly where the insert is in relation to the hole. I don't have a ride up to the parts store to rent one for a little while so I was hoping maybe somebody here could point me in the right direction. Should I just keep tapping and maybe tap the insert out? Or would that push it into the cylinder, and if it did could I retrieve it out? This is a Triton engine with something like 1 ft long spark plug wells. Or, since it's 2001 Lincoln town car, should I take it to a field and have everyone I know come together and use it for target practice, and then roll it off a cliff?
have the same problem?
